DRAW-OFF DEVICE FOR EXPLOSIVE LIQUIDS OR THE LIKE Specification of Letters Patent. Patented June 10, 19199.

Application filed June 23, 1916. Serial No. 105,391.

To all whom it may concern:

Be it known that I, LOUIS KESSLER, a citizen of the United States, residing at'Chicago,

in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Draw-Off Devices for Explosive Liquids or the like, of whichthe follow: in is a description.

y invention belongs to that general class of devices for drawing ofi liquids from tanks or containers, and relates particularly to a draw-off device for explosive liquids. It is suitable for cans, tanks, or other receptacles containing explosive and volatile liquids, such for example as gasolene, benzin, naphtha, and similar oils. The same is particularly applicable for use quantities are drawn off from time to time by retail dealers for supplying their customers. The invention has among its objects the production of a device of the kind described that is simple, safe, efficient, compact, and satisfactory for the purpose indicated. It has particularly as an object the production of a device that will effectually prevent the explosion of the contents, and yet be exceedingly simple and compact, and which can be manufactured at comparatively low cost, It has among its further objects the production of a device in which the spigot at the exterior of the cans may be removed, and yet the contents prevented from leaking out from the can. This is particularly desirable, for should the spigot be broken oil", the can would be sealed against leakage.- Other obects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the dis closures herein made.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding p s a Figure 1 is substantially a sectional view through the device, and portion of the same;

Fig. 2 is a sectional view taken substantially on line 2-2 of Fig. 1;

Fig. 3 is a sectional view taken substantially on line 3-3 of Fig. 1;

on tanks where varying Fig. 4: is a sectional view taken substantially on line 44 of Fig. l, and

Fig. 5 is a side elevation of an auxiliary closure.

Referring to the drawings, portions ofthe side wall 1 and bottom 2 of the tank or receptacle are shown, it being understood that the tank may be of any size or shape, and constructed in any desired manner.

thelbottom of the tank in oneof the side Walls thereof, and in the construction shown consists of a portion carried by the tank and projecting thereinto, and an exterior or spigot portion, which may be removed from the tank if desired.

Referring to Fig. 1, 3 is a member secured to the tank in any suitable manner, and pro jecting thereinto, the same being so arranged that the contents of the tank cannot leak out through the opening about the member. Carried by member-3 is a shell orchambered part 4, provided with a plurality of inlet openings 5 of the desired size and shape. It may be mentioned that member 4 may be made cylindrical, so that it may be inserted through the opening in the tank wall, the opening in most cases being circular. Ar-

.ranged over the openings is a wire gauze 6,

or the equivalent, of comparatively fine or small mesh. When the gauze is arranged as shown it cannot be easily fractured from the outside of the tank through the discharge outlet. In the construction shown the same extends around the part 4, and is soldered or otherwise secured in place. The member 3 is provided with a transverse partition 9, having a plurality of openings 8 therethrough, the inner side being formed with a valve seat 7.; Arranged to cooperate with the valve seat 7 is a valve 10, which is carried by a valve stem 1113, one end ofthe .same being preferably reduced as at 1 2, and

carried by one wall of member 4, while the The draw-off device is preferably arranged'near Arranged to be carried by the part 3 is a detachable part 17, which is preferably formed and communicates with the tubular goose neck 18, at the end of which may be arranged a nozzle 19, if so desired. For con venience in remvoin the part 17, I have shown the same threaded to engage part 3, the exterior being so formed that it may be engaged with a wrench, or the equivalent,-

to remove thepart. The passage of fluid through the part 17 and goose neck 18, is controlled'and normally prevented by a shut off valve 20 arranged to cooperate with the valve seat 21. The valve 20 is provided with a stem 23 on one side, and a similar stem 22 on the other side. Ihave shown a-partition 2i arranged to support the stem 23, the partition having openings 25 therethrough, through which the fluid may pass from the tank. The stem 22 is supported by the structure, a stufling box member27, and packing 28 being provided to prevent the leakage of the fluid thereat, the stem pro ecting to the exterior of the part, as shown. Normally the valve is maintained shut by a spring 26, or the equivalent. As most clearly shown in Fig. 1, the stems 13 and 23 are so proportioned that their ends abut one another.

Any suitablemeans may be employed to actuate valve 20. As shown, the goose neck 18 is provided with lugs (see Fig. 2) atwhich point a yoke 29 is pivoted by the screws 80, or the equivalent. The yoke 29 carries a cross piece 31, arranged to coeperate with the exterior end of the valve stem 22, and the same is also provided with a controlling or operating handle 32.

Assuming that the device is constructed as shown and the oil or fluid contained in the tank. When it is desired to draw off some of'the fluid, handle 32 is moved so that the bar 31 co-acting with the valve stem 22 opens the valve 20. As valve 20 is" opened,

however, stem 23 abutting against stem 13,

simultaneously opens valve 10. The shoulder on the stem at the juncture of 11-'12 limits the movements of the parts, upon its engagement with the casing. The contents of the tank 7 then flow through the screen 6,

past valve 10, and through openings 8, through openings 25 in the partition 24:, past valve 20, and up through the goose neck 7, and are discharged from the inlet into the desired receptacle.

As soon as handle 32 is released, however, the springs 14 and 26 immediately shut both valves, so that the flow of liquid is shut off. As the tank becomes empty, in the case of a small tank, the same may be slightly tilted,

so as to completely empty the tank. If part of the draw-oil device projecting from the exterlor of the tank is removed or broken off accidentally, valve 10 will prevent any leakage of the contents of the tank. The spigot or part at the exterior of the tank may therefore be readily transferred from one tank to another, and if it is desired to store or ship the tanks when filledor when empty, the part at the exterior of the tank may be removed, and a cap similar to 34 shown in Fig. 5, may be" positioned in lieu of the spigot, effectually closing the device and preventing any accidental operation of the valve 10.- Apacking ring 35, may, if desired, be arranged as shown.

The device is particularly suitable for use on small cans or containers of say one, five or ten gallons, indrug 'or paint stores, and the like, for containing explosive fluids, or

fluids of obnoxious odors, and sold at retail in small quantities. It is, however, applicable to other tanks orcontainers, regardless of the size or purpose for whlch same 1s used.

While the wire gauze or fabric 6 in the construction shown is primarily intended to ob viate explosions by preventing flame from entering the tank, for example gasolenecontainers, it might be desirable to omit the I gauze entirely or to use the same merely as a 1. A draw-ofl' device for tanks, comprising a tubular part carried by the tank, a valvepositioned on the inner side ofthe tank and a shut ofi' valve positioned on the outer side of the tank, said valves both arranged to normally prevent the passage of the contents of the tank passing throu h said tubular part, independent means or normally maintaining said valves closed, and means for simultaneously opening said valves from the exterior of the tank.

2. A draw-oil device for tanks comprising a tubular part arranged for attachment to the tank, and having a wire gauze in the path of the fluid passing through the part, and provided with a va ve on the tank side thereof for controlling the discharge of the contents of the tank, means. for normally independently maintaining said valve closed, a cooperating part arran ed on the exterior of the tank, and detacha ly carried by said first part, a valve controlling the passage of the contents of the tank through said cooperating part, means for normally maintaining said valve closed, said second valve arranged to cooperate with the first valve, whereby movement of the second valve to open the described my invention, it is chamber and'spout, a valve stem slidingly supported and extending into the chamber, arranged in its inner movement to contact with and longitudinall move the first valve stem, a cooperating va ve mounted upon the seat, resilient means for normally holding the valve to its seat, and external means for longitudinally moving the second valve stem.

4. In a device of the kind described, a

main chamber adapted to be positioned within a receptacleand having formed therein screened apertures for the admission of fluid, an outwardly seating valve seat formed in the chamber, a ongitudinally movable valve stem slidingly mounted within the chamber, a cooperating valve for the seat mounted in the stem, and resilient means for normally maintaining the valve upon its seat, in combination with an outer chamber into which the main chamber discharges, provided with a dischargespout,

an outwardly seating valve seat between the chamber and the spout, a valve stem slidingly sup orted in the chamber in alinement with the rst valve stem and adapted to con tacttherewith as it is forced inward, a cooperating valve carried by the stem, resilient means for normally holding the valve to its seat, and external means for longitudinally moving the second valve stem.

5. In a device of the kind described, a drum constructed to be positioned within a receptacle, said drum provided with openings to admit fluid thereto and screens covering the openings, an outwardly seating valve arranged within the drum carried by a longitudinally movable valve stem, and resilient means for normally holding the valve closed, in combination with an auxiliarychamber into which the main chamber discharges, a longitudinally movable valve stem supported therein in alinement with the first valve stem and adapted to contact therewith as it is forced inward, an outwardly seating valve carried by the stem, resilient means for normally holding the valve to its seat, external means for longitudinally movin the second valve stem, and a spout into which the auxiliary chamber discharges.

In testimony whereof, I have hereunto :signed my name in the presence of two subscribing witnesses.
